The present invention relates to a paper feeder of a cash register printer, which will be described in more detail. The paper in which a paper roll, which is a slip sheet, is placed is placed in the center of both sides of the fixing part of the paper. Each of the roll guide pieces, which are recessed, is inserted into the printer of the cash register by inserting the roll rotation shafts with the locking projections at both ends in the center of the paper roll, and inserting the roll rotation shafts of the paper rolls in the grooves of the guide pieces. The present invention relates to a paper feeder for a cash register printer capable of smoothly maintaining a conveyance of paper and preventing smooth flow of paper rolls to perform a smooth feeding operation.

In the paper feeding structure introduced into a conventionally known cash register printer, as shown in FIG. 1, a roll paper is rolled into a paper roll case 12 in which the paper 11 is placed. A government part 13 is formed, and the paper 14 is drawn out from the paper roll 11 settled in the roll fixing part 13 so as to be fed into the printer.

Therefore, the paper roll 11 placed in the roll fixing portion 13 of the paper roll case 12 is a roll fixing portion 13 by the tension of the cash register printer (not shown) in the same manner as drawing out a paper such as a facsimile or the like. The paper 14, which is the slip sheet, enters the printer as it rotates.

However, in the conventional paper supply structure having the above structure, since the paper roll 11 is simply placed in the roll fixing portion 13 in which the paper roll 11 is placed, the roll fixing portion 13 There is a disadvantage that the noise is generated by the flow of paper roll in the left and right and back and forth within.

In addition, the paper roll 11 settled in the roll fixing unit 13 as described above is caused to cause a malfunction of the cash register when the paper 14 supplied to the printer by the left, right flow is fed at a skewed. There were many problems.

The present invention has been made in order to improve the conventional problems as described above, the purpose of which is, the groove is vertically long to the inside of the paper roll fixing part of the center of the paper roll case in which the paper roll is placed slip sheet Each roll guide piece is inserted, and roll rotation shafts with projections protruding at both ends are inserted in the center of the longitudinal roll, and the roll rotation shafts of the paper rolls are inserted into the grooves of the guide pieces. It is possible to maintain the transfer smoothly, prevent the flow of the paper roll to perform a smooth feeding operation, as well as to prevent the malfunction of the cash register due to the skew of the paper entering the printer in advance to prevent the cash register It is to provide a paper feeder of a conventional printer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic perspective view of the paper feeder of the cash register printer according to the present invention, wherein a paper roll 1, which is a slip sheet, is placed in the roll fixing part 3 of the paper roll case 2 and supplied into the printer. In the paper feeder of the printer for a register, roll guard pieces 6 each of which has grooves 5 vertically elongated inwards are placed on both sides of the center of the roll fixing part 3 of the paper roll case 2, respectively. In the center of the paper roll (1), roll rotation shafts (8), each of which has protrusions (7) protruding from both ends thereof, are inserted into the locking members of the roll rotation shaft (8) in the groove (5) of the guide piece (6). Group 7 is made of a configuration to be fixed to the insertion.

In the figure, reference numeral 4 denotes paper which is a slip sheet drawn out from the paper roll 1.

Referring to the operation and effects of the present invention composed of such a structure as follows.

That is, as shown in FIG. 2, when the paper roll 1 is installed in the paper roll case 2, the rotating shaft 8 which has the engaging projection 7 protruded in the both ends to the center of the paper roll 1 is provided. ), And then insert it into the roll guide piece 6 placed on both sides of the center of the roll fixing part 3 of the paper roll case (2) to rotate into the groove (5) of the roll guide piece (6) The engaging projection 7 of (8) is rotatably inserted so that the paper roll 1 is fixed to the roll fixing part 3 in a fixed state.

Therefore, when the paper 4, which is the slip sheet of the paper roll 1, is pulled out by the tension of the printer, the paper roll 1 is fixed and rotated in the locked state on the pivot shaft 8, so that the paper roll 1 is rotated. As a result, the flow afterwards is prevented in advance and can be withdrawn smoothly.

As described above, according to the paper supply apparatus of the cash register printer according to the present invention, it is possible to smoothly maintain the conveyance of the paper flowing into the printer of the cash register, and to prevent the flow of the paper roll to perform a smooth feeding operation. As well as being able to, there is an excellent effect that can prevent the malfunction of the cash register due to the skew of the paper entered into the printer.
